From 193c3cc12583344be01206078d9ad3fec5dbc397 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 28 Jan 2008 10:16:37 +0000 Subject: [ARM] Fix timer damage from d3d74453c34f8fd87674a8cf5b8a327c68f22e99 Move the xtime write mode seqlock into timer_tick(), so it only surrounds the call to do_timer(). This avoids a deadlock in update_process_times() ... hrtimer_get_softirq_time() which tries to get a read mode seqlock on xtime, thereby preventing booting.
